LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 236,396, dated January 4, 1881,

Application filed J 11110 24, 1880.

To all whom it may concern:

Be it known that I, WILLARD D. DOREMUS, of IVashington, in the county of Washington, and in the District of Columbia, have invented certain new and useful Improvements in Apparatus for Lighting and Extinguishing Lamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figures 1 and 2 are perspective views of the front and rear sides, respectively, of my improved lantern. Figs. 3 and at are like views of the lamp separated from the casing, the wick-tube being covered in the first-named view and uncovered and the wick lighted in the last-named view. Figs. 5 and 6 are plan views of the upper side of said lamp, and show, respectively, the positions of parts shown in Figs. 3 and 4. Figs. 7 and S are elevations of the rear side of the lamp, and show, respectively, the position of parts when the wick-tube is closed and when it is uncovered and the hammer raised for the explosion of a pellet. Fig. 9 is a like view of the same after said hammer has fallen and with the barrel removed. Figs. 10 and ll are vertical sections upon lines a: .r and z 2, respectively, of Figs. 5 and 6; and Fig. 12 is a perspective view of the ext-inguisher-cap and its operating mechanism separated from the other parts.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to increase the efficieucy of self-lighting lamps; and to this end it consists, principally, in combining with the outer horizon tally-open en (1 ofa curved wick-tube an extinguisher-cap arranged to move in a substantially horizontal plane over or away from the same, sulistantially as and for the purpose hereinafter specified.

It consists, further, in the means employed for moving the extinguisher-cap over or from the outer end of the wick-tube, substantially as and for the purpose hereinafter shown.

In the annexed drawings, A represents a rectangular casing constructed ofor from sheet metal, having, preferably, a curved upper end,

(Model) and provided in front with a glazed-light opening, B, and at said upper end with a ventilator, O, as seen in Figs. 1 and 2.

Fitted into the open lower end of the casing A is a reservoir, D, which corresponds in plan view to the size and shape of the opening, and is held in place, when inserted therein, by two springs, E, placed at its ends, or by other equivalent and well-known means.

Within the rear side, at the longitudinal center of the reservoir D, is formed a right-angled recess, d, for containing the lighting mechanism, hereinafter described, and immediately in front of the same is provided a wick-tube, F, of usual form, except that its projecting portion extends in a curve forward over said recess'and delivers the wick fhorizontally. Said wick is raised or lowered by means of an ordinary wick-wheel, the shaft of which, G, extends horizontally through the side of the casing A.

Secured upon the front side of the recess cl, immediately below the wick-tube F, is a casing, H, which has a cylindrical form, has interiorly sufficient dimensions to enable it to receive and contain a roll of percussion-tape, I, similar to that used in cigar-lighters, and has a removable head, h, for the purpose of affording access to its in terior. A peripheral opening, it, near the upper side of said casing or barrel, enables the outer end of said tape to pass outward.

J ournaled upon the axial screw of the barrel H, between the latter and the side of the reservoir D, is a lever, K, which has the form shown in Fig. 9, its lower end projecting through a slot in the bottom of said reservoir, while its upper end extends forward over said barrel, and such extended portion is has an inclination downward and in line with the wickwheel shaft G. From the edge of said lever opposite to said shaft an arm, 70, extends forward along the periphery of said barrel, and thence upward, with its end resting upon said periphery, so that when said lever is oscillated upon its axial bearing said arm It operates as a pawl, and engages with and moves forward the end of the percussion-tape l.

Secured upon a fixed support is a springarm, L, which extends over the barrel H, and has its end I in contact with the upper portion of the periphery of the same. From the rear edge of said arm L, near its hammer end I, a lug, l, projects rearward and engages with the inclined part 70 ot' the lever K, the arrangement being such as to cause said inclined part to pass beneath said lug and to raise said arm L as the lever K is moved in one direction, and to pass over said lug when said lever is moved in an opposite direction. \Vhen the inclined portion k of the lever K has raised the arm Ltoits highest position itpasses from beneath the lug l, and permits said arm to spring downward and to impinge upon the percussion-tape I, which, by the action of the pawl-arm 7, has been fed forward to the right position, the result being an explosion ot'one ot' the percussive pellets and the ignition ot' the wickf by the flame caused by said explosion, which operation may be repeated while said tape lasts. The used portion of the tape I passes around the barrel H and downward through an opening, 61/, in the lower side of the reservoir 1), where it may be torn off.

In order that the end of the wick-tube F may be covered and the light extinguished, when desired, a cap, m, adapted to cover the same, is secured to or upon the end of an arm, m, which extends horizontally from a plate, M, that is pivotrd upon the end of the recess (1 opposite to the spring-arm L, said plate being so pivoted as to cause said cap to be moved rearward from or forward over said wick-tube as said plate is oscillated upon its bearing. The plate M is automatically moved by means of two lugs, m and m which extend horizontally inward from points below and aboveits pivotal center, and are engaged by the pawlarm 70 as the latter nears the lower and upper limits of its motion.

By the construction described the Wickfis uncovered and lighted by the movementot' the lever K in one direction, and is covered and the tlame extinguished when said leveris moved 5 in an opposite direction.

The casing A is provided with two horizontz'illy-swinging handles, N, which are pivoted or hinged upon its rear side, and may be turned flatly againstthe same, and has also a bail, O, that is pivoted near the upper end of said oasing, and when not used may be turned downward against the rear side of the same, and its end engaged by alug, a, that locks it in place, such construction enabling the lantern to be stored in a space but slightly greater than said casing A.

Having thus fully set forth the nature and merits of my invention, what I claim as new is 1. In combination with the outer horizontally-open end of a curved wick-tube, an extinguisher-cap arranged to move in a substantially horizontal plane over or away from the same, substantially as and for the purpose specified.

2. As a. means for causing the end of the wiclrtube F to be covered or uncovered, the pivoted plate M, provided with the arm-m, cap m, and lugs m and W and the lever K, pivoted centrally and naving an arm, 70, which engages with said lugs and causes said plate to oscillate upon its bearing, substantially as specified.

in testimony that I claim the foregoing, I have hereunto set my hand this 8th day of August, 1579.

WV. D. DOREMUS.
